ESP8266 refresh rate issue

[test1025]

Hello! I am not good at English, so I use a translator. If I don't understand it, I'm really sorry~! When I was using ws2812 to flash into the demo on GitHub, although the light turned on correctly, it looked very "flickering" and felt like the refresh rate was very low? There is no difference in the appearance after adjusting the speed and replacing the light bar, but there is no problem with using NeoPixel's Rainbow. May I ask where the problem is? I didn't add any other code at this time, and all modes have this issue, and the power supply is also normal Thank you! Wishing you success in your work I wish you all the best

What hardware are you using? It would also be helpful to cut/paste the sketch you're using.

I used the NodeMCU ESP8266 development version for development, and I tried two ESP8266 development boards The light strips were also replaced with different ones and the same results were obtained. This is my code, only the demo code of the project will be tested It looks like a flickering light, it looks strange, just like a low refresh rate? Have you ever encountered such a situation? I once encountered this issue in the Arduino support library of a 51 microcontroller, and it was not resolved at the time Maybe I should use ESP32 for testing next week..?

Wish your family and beauty, brilliant career, happiness and health!

include

define LED_COUNT 25

define LED_PIN 5

WS2812FX ws2812fx = WS2812FX(LED_COUNT, LED_PIN, NEO_GRB + NEO_KHZ800);

void setup() { ws2812fx.init(); ws2812fx.setBrightness(100); ws2812fx.setSpeed(200); ws2812fx.setMode(FX_MODE_RAINBOW_CYCLE); ws2812fx.start(); }

void loop() { ws2812fx.service(); }

I have also tried different ws2812fx.setSpeed（）counts, there is no difference

Ah, I see. Setting speed=200 is very fast for the RAINBOW_CYCLE effect with only 25 LEDs, which is causing a strobe-like effect. Try setting speed=5000 and I think you will have better luck.

ws2812fx.setSpeed(5000);

Remember increasing the speed parameter makes the LED animation run slower, which is probably the opposite of what you expected. A common mistake.

I'm sorry, GitHub didn't send me an email reminder to reply. I just saw it today. Perhaps it's not a matter of speed, but I soldered 125 lights, which seems to have little impact. Thank you! Sorry for not replying for a long time! Thank you for developing the ws2812fx library, which has made it convenient for me to develop LightCube

You're building a light cube? I'd like to see it when you're done. I'm always curious to see what creative people are doing with ws2812fx.

I've built an LED cube too, although it uses the fastLED library, not ws2812fx. You can see it in action here: https://www.champlainsystems.com/ledcube/

yes!Use the ESP8266 microcontroller to connect to WiFi and control the color of the lights through Xiaoai, a voice assistant from China It was given as a birthday gift to my classmates

That's very cool. Thanks for sharing.
